MW DXing and Broadcasting
From The RadioReference Wiki

Introduction
Welcome to the MW DXing and Broadcast wiki. The MW band (540-1700 khz) is where broadcasting began in the US, and DXing in this band has been around ever since. The links on this article should help get you started in this area. In addition there are media-related links for additional background.
The 1700-2000 khz range is often referred to as the 'Med-fer' part of the spectrum. While there is limited experimentation here, telemetry and navigational beacons are also heard here. This service is slowly dying out as less expensive, and more reliable technology is being used instead.

- One thing that is similar to MW and HF DXing (on freqs below 10 Mhz) is that there must be a darkness path between you and your target to have a shot at hearing a station. Our HF Propagation has many links for this
